Enterprise users should note that, although Apple has fixed these vulnerability with the 11.3.1 update, the security benefits are not reflected on their devices unless users update the OS to this latest version. Thus, before attackers exploit these vulnerabilities, enterprise users should go to “Settings > General > Software Update” and update their iOS devices to the latest version.

OS updates are among the easiest and most cost-effective ways to prevent attacks from exploiting holes in older operating systems and we certainly recommend updating to this latest OS release given the numerous security updates it provides.
